Guest jpmorgan Posted January 14, 2006 Share Posted January 14, 2006 I continue to get a E022 error even after replacing the ECM. The screen voltage on ED01 is .2 and it only goes to .4 with higher RPM's. My manual says to adjust the voltage, but I can't find out where the potentiometer is located.Or am I chasing kremlins and need to look else where?ThanksSorry....I have a 89 Reatta Link to comment Share on other sites More sharing options...
Guest F14CRAZY Posted January 14, 2006 Share Posted January 14, 2006 With the ignition on, engine off, ED01, the TPS voltage, should be 0.34-0.46. When stepping on the gas gradually, it should smoothly go up to around 5 volts. If it's not changing even when floored, I'd replaced the TPS Link to comment Share on other sites More sharing options...
2seater Posted January 15, 2006 Share Posted January 15, 2006 The TPS is located on the lower front of the throttle body. It operates from the shaft that runs through the throttle body for the throttle blade. Throttle linkage on upper rear and TPS at the other end. It is fastened with two non-magnetic stainless steel screws, be careful you don't drop them.The holes in the TPS itself are actually slots so a small amount of movement is available to adjust the voltage.
